DUMPING WAGON-BOX;

SPECIFICATION forming part of Letters Patent No. 747,510, dated.December 22, 1903 Application filed November 2, 1903. Serial No.179,621. (No model.)

522) on whom it may concern.-

Be it known that we, MAURICE B. TODD, CHARLES L. TODD, and EDWARD H.NEFF, citizens of the United States, residing at North 5 Topeka, in thecounty of Shawnee and State of Kansas, have invented anew and usefulDump Wagon-Box, of which the following is a specification.

This invention relates to dumping-wagons IO of the type employed forhauling sand, grain,

&c., and has for its object to; produce a comparatively simpleinexpensive device of this character which may be readily manipulatedfor discharging the contents of the wagonbody.

To these ends the invention comprises the novel features of constructionand combination of parts more fullyhereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of awagon-body embodying the invention. Fig. 2 is a longitudinal sectionalelevation of the same, certain parts being shown in dotted lines. Fig. 3is a vertical transverse section taken on a line with the pivotal axisof one of the bottom sections. Fig. 4 is a detail perspective of one ofsaid sections. Fig. 5 is a detail view.

Referring to the drawings, 1 designates the wagon-body, comprising sides2, ends 3, and

0 a sectional bottom 4:. These parts, which are of wood or othersuitable material, may be assembled in any desired manner, butpreferably as herein shown, in which the sides 2 are connected at thefront and rear by inner and outer transverse beams 5 and 6 and the endsare downwardly and inwardly inclined and have their lower edges attachedto the inner beams 5, theparts being braced and strengthened by diagonaltie-rods 7, extending from the outer upper corners of the body inwardand downward toward the center of the latter to a point of engagementwith lower longitudinal side beams 8.

The bottom 4 is composed of a series of pivoted sections 9, arrangededge to edge in horizontal alinement, with their meeting edges in closeassemblage, thus rendering the bottom normally practically continuous.Each section 9 consists, preferably, of a single piece of board, havingits edges metal-bound, as at 10,

while extending transversely through the section is a plurality ofbracing or strengthening rods 11, which serve to prevent warping orsplitting of the sections. Each section has riveted or otherwise secured to its lower face a strap-metal member 12, which preferably extendsback and forth across the section, as herein shown, thus further bracingand strengthening the latter, and terminating at its ends in pivotingpintles or trunnions 13, disposed in end-to-end alinement parallel withthe longitudinal axis of the section, these trunnions being extendedoutward from end edges of the section adjacent to one of itslongitudinal sides, whereby the section will in practice heeccentrically pivoted and will in moving to an open position swingdownward substantially wholly beneath the box or body. The trunnions 13are journaled in suitable bearings 14, more fully hereinafter described,in the sides 2 of the box, between the walls of which openings and thetrunnions there are disposed upon the latter wearing sleeves or thimbles14;, de-

signed to sustain the wear incident to the operation of the parts and tobe readily replaced or renewed when circumstances require. One

of the trunnions 13 of each of the sections, with the exception of thefront section of the series, is provided with a preferably integral 8ocrank-arm 15, which arises from the trunnion normally in a substantiallyvertical plane and is in turn provided at its upper end with ahorizontal outwardly-projecting wrist-pin 16. The arms 15 ofall of thesections lie upon the outer face of one of the sides 2 and areoperatively connected bya shaft or other suitable element 17, havingatsuitable intervals openings which pivotally receive thewrist-pin 16.

It is apparent from'this arrangement that the 0 connecting shaft orelement 17 may be Inanipulated for simultaneously swinging all of thesections on their pivots to an open or closed position.

The trunnion of the front section 9 instead of having a crank-arm 15formed integral therewith terminates in a squared or other non-circularportion 18, which fits a corresponding opening formed at the lower endofan elongated crank-arm or lever 19, with :00

which the forward end of shaft 17 is pivotally connected. This levertravels upon and is guided by a semicircular rack or guide 20, bolt-edor otherwise secured to the wagonbody and provided with a notch 21,adapted for engagement by a dog 22, operated in the usual manner forlocking the lever in its normal position.

As seen more clearly in Fig. 5, the bearings 14 are each seated in amortise opening or recess 23, formed in the side beams 8, and consisteach of a pair of castings 24, disposed one upon the other, with theirmeeting faces having semicircular openings transversely disposed andadapted to coincide to form circular bearing-openings, which receive thetrunnions 13. The castings 24 are maintained in assemblage and securedin the openings 23 by vertical bolts 25, passing downward through thealined openingsin the casting and beam. Thus a strong durable bearing isprovided which permits of the bottom sections being readily removed ifcircumstances require.

From the foregoing it is apparent that when the lever is locked in theposition as in Fig. l the sections 9 will all be maintained in closedposition, but that when the lever is released and swung backward, asindicated by the arrow, the crank-arms 15 will, through the medium ofshaft 17, be simultaneously actuated for swinging the sections to anopen position, as heretofore explained, thus discharging the contents ofthe box. In attaining these ends various minor changes may be made inthe details of construction herein set forth without departing from thespirit of the invention. For example, the arms 15 instead of beingformed integral with the trunnions 13 may be engaged therewith in themanner similar to that of engagementof lever 19 with its trunnions, andthis or like changes will fall within the scope of the invention.

Having thus described our invention, what we claim is- 1. Thecombination with a vehicle-body having sides provided withbearingbpenings, of a bottom comprising a plurality of sections,trunnions carried by the sections and pivotally engaging thebearing-openings, the trunnions of each section being disposed inend-to-end alinement parallel with and adjacent to one of itslongitudinal edges, an opcrating-lever carried by a trunnion of one ofthe sections, cran k-arms associated with the corresponding trunnions ofthe remaining sections, and an element connecting said lever andcrank-arms for uniform movement to operate the bottom sectionssimultaneously.

2. The combination with a vehiclebody having sides provided withbearing-openings, of a bottom comprising a plurality of sections,strengthening members attached to the sections and terminating intrunnions pivotally engaging the bearing-openings, the trunnions of eachsection being disposed in endto-end alinement parallel with andadjacentto one of its longitudinal edges, an operating-lever detachablyengaged with a trunnion of one of the sections,crank-arms formedintegral with the corresponding trunnions of the remaining sections, anda shaft connecting said lever and crank-arms for uniform movement tooperate the bottom sections simultaneonsly.

3. The combination with a vehicle-body havingsides provided withbearing-openings, of a bottom comprising a plurality ofsections,strengthening members attached to and extending back and forthacross said sections transversely and terminating in trunnions pivotallyengaging the bearing-openings, the trunnions of each section beingdisposed in end-to-end alinement parallel with and adjacent to one ofits longitudinal edges, wearingsleeves removably mounted upon the trun--nions within the bearing-openings, an operating-lever detachably engagedwith a trunnion of one of the sections, crank-arms formed integral withthe corresponding trunnions of the remaining sections, and a shaftconnecting said lever and crank-arms for uniform movement to operate thebottom sections simultaneonsly.

In testimony that we claim the foregoing as our own we have heretoafiixed our signatures in the presence of two witnesses.
